Apple just published a letter to customers apologizing for the “misunderstanding” around older iPhones being slowed down, following its recent admission that it was, in fact, slowing down older phones in order to compensate for degrading batteries. “We know that some of you feel Apple has let you down,” says the company. “We apologize.”

Apple says in its letter that batteries are “consumable components,” and is offering anyone with an iPhone 6 or later a battery replacement for 29 starting in late January through December 2018 — a discount of50 from the usual replacement cost. Apple’s also promising to add features to iOS that provide more information about the battery health in early 2018, so that users are aware of when their batteries are no longer capable of supporting maximum phone performance.

It’s bullshit Apple had to be called out this, but they’ve apologized and offered a reasonably priced solution.

I just upgraded from an iPhone 6 Plus to an iPhone X, but I think it’s still worth it to replace the battery on my 6 Plus.
